she has trained fbi agents. did you ask for copies of those documents? >> yes. >> and what did you find? >> when i looked at the assignment of mortgage, and this is the assignment, a copy from my case, i looked at even the date they put in, which was 10/17/2008, was several months after they sued me for foreclosure. so what they were saying to the court was, "we sued her in july of 2008, and we acquired this mortgage in october of 2008." it made absolutely no sense. >> curious, she used her legal training to go online and researched 10,000 mortga >> then i began to find the strange signatures. >> one of the strangest signatures belonged to the bank vice president who'd signed szymoniak's newly discovered mortgage documents. the name is linda green, but on thousands of other mortgages, the style of green's signature changed a lot, and even more remarkable, szymoniak found that linda green was vice president of 20 banks all at the same time. >> all within the same week. i mean, this is a very, very active person. >> where did all those documents come from?
